... in air, then decreases when cooling occurs due to a change in media. An increase in the flow rate further decreases the temperature difference. The set point is adjusted for the switch to alarm at the ...

2. ultrasonic streamflow monitoring system

... by direct measurement of velocity over dam crest, this system can measure discharge not only for modular flow in which free fall occurs, but also for submerged flow affected by downstream as far as depth ...

3. Hamilton Visiferm DO Sensors

... sensors are not considered particularly accurate, since in the absence of oxygen no O2 molecules can be reduced, as a result no current flows. The same happens when a cable break occurs. This is different ...
